Closed vs Isolated Systems

[yazzs]

Hello!
I'm having some trouble understanding the difference between closed systems and isolated systems. Would anyone be able to provide me with an example of each?
Thank you!

An open system is when matter and energy may be exchanged with the surroundings (e.g. a beaker of water - water can evaporate and the beaker does not insulate).

A close system is when only energy may be exchanged with the surroundings (e.g. a sealed beaker of water - beaker does not insulate).

An isolated system is when nothing (neither matter nor energy) may be exchanged with the surroundings (e.g. combustion of glucose in a bomb calorimeter).

[Ethan Chen 1K]

A closed system is where only energy can be exchanged with its surroundings; matter cannot be exchanged. A hot bowl of soup in a glass container with a lid is an example. Heat can still travel out the container, but your soup can't. An isolated system is where nothing, including energy and matter, can be exchanged with its surroundings. A thermos bottle can be a real life example of this because it keeps your drink hot or cold even after hours; heat is not being transferred in or out the bottle.

[Annabelle_Wilson_1E]

A closed system does not let matter move in and out of it, whereas it does occasionally let energy in and out of it. An isolated system does not let matter nor energy enter or leave. They are very similar, but different in terms of energy. An example of an isolated system would be a thermos (or a hydroflask).

[liapletcher 1A]

A closed system is one that can exchange energy but not matter with the surroundings whereas an isolated cannot exchange matter or energy with its surroundings.

[Varun Sekar 2E]

An open system is one in which energy and matter can be exchanged with its surrounding. A closed system is a system in which energy can be exchanged with its surroundings but not matter. An isolated system is a system that doesn't exchange matter or energy with its surroundings. I hope this helps!

[perla_1L]

A closed system does not let substance/property in and out, but can still exchange energy. An isolated system does not do either and stays consistent.

[905934944]

closed system is when energy can be exchanged by isolated system is when nothing can be exchanged. the universe is an example of an isolated system

[Mehreen_Suzaan_1A]

A closed system would be like a closed beaker where energy can flow but the substances inside the beaker cannot. An isolated system would be like the universe where there are no surroundings (as far as we know) for energy or matter to flow in or out of. Isolated systems are harder to create.

[Jake1K]

Closed system you can exchange heat and do work. Isolated systems you can't exchange heat or do work.

The drawing I made attached helped me remember easily and redrawing it may help you memorize as well!

[Saahithi Kari]

A closed system is a system that can exchange energy with its surroundings. This means that while the matter within the system cannot be exchanged, energy can be because the system is not insulated to prevent that from happening. An example of a closed system would be a sealed, but not insulated, beaker because it can exchange energy with its surroundings since the beaker is not insulated. An isolated system is a system that cannot exchange any matter or energy with its surroundings because it is insulated, so the transfer is not possible. An example of a closed system would be the combustion of glucose in a bomb calorimeter because the bomb calorimeter is insulated to prevent the energy from the combustion reaction to be transferred to the surroundings.

[Natalie Hurd 1H]

Closed systems can only exchange energy with surroundings and an example is a sealed beaker. Isolated systems can not exchange anything with surroundings and an example is the combustion of glucose in a bomb calorimeter. The main difference between these two are that closed is less intense than isolated as energy still can be exchanged.

[Helen Heath 2B]

a simple example to help explain this is a pan on a stove with and without a lid. a pan without a lid is an open system because water can evaporate or be added to the pan, but with the lid on, water can never leave or enter. however, heat can be added or taken away from either example with or without the lid because heat is energy and a closed system lets energy leave or enter but not water (matter).

[Nina Vu-Gia 1C]

a closed system means that the system is sealed from the surroundings and nothing can be added or removed from the system except energy in the form of heat. An example of this would be a pot of water on a stove with the lid on. There cannot be any water added or removed from the pot because it is closed, however the pot and the water inside are being heated up by an outside energy source.
a isolated system means that the system is sealed from the surroundings in all ways including the inability to exchange energy in the form of heat. An example of this would be any insulated container such as a thermos. The thermos is sealed and therefore nothing is being added or removed, also the contents of the thermos stay hot and don't lose any energy through heat loss to the surroundings.

[Keanu Ngo 3B]

A closed system means only energy can be exchanged between the system and its surroundings. An isolated system means that nothing can go in an out of the system from the surroundings.

[Shania Hao 3L]

A closed system is able to exchange energy with its surroundings, but it is unable to exchange matter. An isolated system is unable to exchange anything with its surroundings, whether it be energy, heat or matter. An example of a closed system is a covered pot because it can exchange energy with the surroundings and heat up/cool down, but no matter is being exchanged. Although it was mentioned that there is no truly isolated system, an example of such is a calorimeter because it is designed to be insulated and to not exchange any energy or matter between its system and the surroundings.

[joannar]

Hi!
So the way I understand it is that an Isolated system is a system in which no matter or energy is being exchanged with the surroundings (so no transfer of energy and matter) (an example can possibly be a closed thermo flask) . A closed system is a system in which only energy is being exchanged with the surroundings (so there is no transfer of matter)(example of closed system can be a covered beaker of water)

[Kimberly_Wu_3H]

A closed system means only energy can be exchanged between the system and its surroundings, heat can enter but matter cannot. An isolated system means that heat and matter cannot go in an out of the system from the surroundings.

[Carmen Lo 1L]

Closed System: ONLY ENERGY can exchange with surroundings (NOT MATTER)
ex: a closed water bottle
Insulated System: NEITHER ENERGY OR MATTER can exchange with the surroundings
ex: bomb calorimeter

It is important to note that insulated systems are very rare and even in examples like the bomb calorimeter, it is only considered insulated for a duration of a time since with time, there would still be heat exchange. A more "real-life" example of this would be the insulated water bottle. It is supposed to keep your hot drinks at the same constant temperature, however there is still heat exchange happening since your insulated drink would still drop in temperature with time.

[nikita_manyak28]

Though a closed and isolated seem very similar as they are both closed off to outside factors, there is a big difference in what is not being allowed to enter the system. In a closed system, matter is not able to enter or leave, but energy is still able to freely move through the system. In an isolated system on the other hand, does not allow energy or matter to enter or leave the system.

[Amber1L]

Only energy can be transferred in a closed system whereas neither energy nor matter can be transferred in an isolated system.

[Sarah Khan]

For a closed system imagine a beaker with a cap (the beaker is closed, right?). You wouldn't be able to add matter because it's CLOSED. It can only exchange health and energy with its surroundings. Another good example of it would be an ice pack. You cant add matter inside the ice pack because it's closed but it can exchange temp with an injured person.
For an isolated system, it doesn't let anything in or out so no exchanging matter or energy with its surroundings (an example would be a hydroflask- the waterbottle company)

[Kiiana Hilario 2E]

An open system can exchange both energy and matter with its surroundings. A closed system can only exchange energy with its surroundings.

[Andrew Dinh 2L]

A closed system is a system where matter cannot be exchanged between the system and surroundings, but energy can. An example of this is pot of boiling water with a lid on top. With this example, no water can leave the system, but energy can leave in the form of heat. An isolated is a system where matter and energy cannot be exchanged. An example of this would be a coffee cup sealed in a perfectly insulated sleeve. In reality, no system is perfectly an isolated system, since all systems interact with other things surrounding them; an isolated system would have to basically be in a vacuum without any interactions with anything else.

[Elliana_Tsang_1L]

In a closed system, the container is closed off to the surroundings, so matter cannot enter. However, energy in the form of heat is able to pass through the container. This may be like a pot with the lid on and water boiling inside; you can feel the heat passing through the metal from the contents inside. Similarly, the isolates system does not allow for matter to enter or leave the system, but unlike the closed system, the isolated system does not allow heat exchange between the system and the surroundings. For example, a styrofoam cup with a styrofoam lid does not allow for heat transfer.

[Jaylin Heggins 1A]

A closed system is one where energy can be exchanged with the surroundings. An example of a closed system is a sealed beaker of water that is not insulated. An isolated system is one that cannot exchange anything with the surroundings. An example of an isolated system is the combustion of glucose in a bomb calorimeter.

[Daniel Hong 3F]

A closed system is where the energy can be exchanged by the surroundings where for example a sealed beaker of water being closed. The isolated system is the one that cannot exchange anything with the surroundings like the combustion of glucose in a bomb calorimeter.

[405773279]

a closed system has a fixed amount of matter but exchanges energy with surroundings but an isolated system does not participate in any energy/matter exchange at all

[Jason T 1I]

A closed system can exchange energy with its surroundings but is unable to exchange matter. While an isolated system can exchange neither energy nor matter with its surroundings.

[Maggie_Harned_3H]

Hi,
One of our syllabus questions does a good job at showing different examples for isolated, close, and open systems. An example of an isolated system where neither matter nor energy can exchange with surroundings is coffee in a very-high-quality thermos bottle. An example of a closed system which has a fixed amount of matter but can exchange energy with surroundings is mercury in a thermometer. An example of an open system which both matter and energy can exchange with surroundings is a living plant.

[906032986]

In a closed system, matter cannot go in, but it can still transfer energy with the surroundings. In a closed system, matter cannot go in and it cannot transfer energy with the surroundings.

For example, we have 3 systems (open. closed, and isolated), all surrounded by O2 gas. The surroundings are at a higher temperature than each of the systems. In the open system, the O2 gas will be able to go into the system AND heat from the surroundings will be able to warm up the open system. In the closed system, the O2 gas will NOT be able to go into the system, but it can still have heat transferred from the surroundings the same way that the open system can. In the isolated system, O2 gas will NOT be able to go into the system and there is NO heat transfer from the surroundings to the system.

[Brandy_Lopez_1C]

A close system refers to the exchange of energy with the surroundings while an isolated system doesn't have any energy exchange with the surroundings.

[Itxhel Jimenez 1B]

Hi!

I believe a closed system is a system where energy can be exchanged with the environment (Not mass that is open system) while in an Isolated system neither energy nor mass can be exchanged. Therefore the change in internal energy of isolated systems is always 0

[Alec Villarreal 2H]

An isolated system is a system in which heat, energy, and matter can't be exchanged with the surroundings, while a closed system is a system in which heat and energy can be exchanged with the surroundings while the matter can't be exchanged. They are similar to each other in that both systems don't allow matter to be exchanged, but differ in how one can exchange heat and energy with the surroundings while the other can't.

[Andres Ibarra 2F]

Hey!
The difference between an isolated system and a closed system is:
An isolated system is where nothing (such as matter or energy) can be exchanged (enter or leave) with the surroundings and the system. An example of an isolated system is a bomb calorimeter.
A closed system is a system where only energy can be exchanged with its surroundings but matter cannot. An example is a sealed beaker or something which is easier to visualize is a hydroflask where only energy can interact with the water or liquid inside.

[705748759]

an isolated system doesnt allow heat or work to pass through. a closed system does allow heat and work to pass through but the matter can not be exchanged

[Sofi Ghasemzadeh 2G]

A closed system is one in which there is no flow of matter, but there is energy exchange between the system and its surroundings.

An isolated system, however, is a system in which there is absolutely no exchange of anything--matter or energy--between the system and its surroundings.

An example of a closed system would be a frying pan with the lid on it. All the matter remains in the pan--none can leave. However, energy (in the form of heat) is still able to move in an out of the system.

An example of an isolated system would be a thermos flask. Isolated systems rarely occur in nature, but a thermos flask is a good example of a common one. Like the closed system, no matter can leave or enter the system, but additionally, no energy can either. All energy (heat) is conserved in the thermos, with no potential of it exiting.
